With my first MB 13' aluminum (this was the first generation where they didn't name it the MBP) I decided to get the speck satin red case. This case was fantastic and really fit the computer. Although the top lid was somewhat hard to take off, I knew the fit was perfect. Now I got my brand new MBP 13' and so I thought I would get the see thru case (the one with no color.) When I received this and put it on, i noticed that it didn't fit as well as it did on my other macbook, noticeably on the top. It seemed that there was a least 1/4 of an inch from the actual macbook and the case. So I emailed speck and they had great tech support. And now I'm here today, about two weeks later with my replacement, but the problem is still there. The case is just not as closely fit as the older one. It's to the point where when I open the lit of the MBP, the top case can come off (only the top of the lid.) Im starting to think that they made it more loose on purpose and I can't bother to email them for another replacement. If something happens to my computer, such as a scratch because of the case, I'll be sure to email them about it.
